CensusCD 2000 / Redistricting Blocks is based on the first detailed
data available from the 2000 Census, the Redistricting (Public Law 94-171) data.
CensusCD 2000 /Redistricting Blocks reports the population, racial and ethnic
data at the Census Block Level (all 8.2 million). Block level data allows for a
significantly higher resolution of demographic analysis than viewing data at the
Block Group level.
CensusCD 2000/Redistricting Blocks also includes 1990 Redistricting
data normalized to 2000 geographies thru a sophisticated (and proprietary) 1990 to
2000 Block weighting process, built from the analysis of both TIGER 1992 and
CensusCD 2000/Redistricting Blocks is the most comprehensive set of
Census 2000 data boundaries available.
